3x10 to the 7 power x9x10 to the 8 power

1 answer

To multiply the numbers \(3 \times 10^7\) and \(9 \times 10^8\), you can follow these steps:

  1. Multiply the coefficients (the numbers in front): \[ 3 \times 9 = 27 \]

  2. Multiply the powers of ten by adding the exponents: \[ 10^7 \times 10^8 = 10^{7 + 8} = 10^{15} \]

  3. Combine the results: \[ 27 \times 10^{15} \]

So, the final result is: \[ 27 \times 10^{15} \]

Alternatively, you can express \(27 \times 10^{15}\) in scientific notation as: \[ 2.7 \times 10^{16} \]

Both forms, \(27 \times 10^{15}\) and \(2.7 \times 10^{16}\), are correct.
